R devel - Jul 2014 - Removed 'extern' on R_running_as_main_program in Rinterface.h -- intentional?

Hi R-devel,

In this commit:
https://github.com/wch/r-source/commit/c67a107dd7b0f074cec9359b8e2ca07c6243283c

R_running_as_main_program was moved from Rmain.c to Rinterface.h, and lost
its 'extern' declaration. This change is causing us linker problems
(since
we now have duplicate symbols for R_running_as_main_program). Was this
intentional? If so, what else should applications embedding R be doing to
indicate they are running as the main program?

In addition, I guess the documentation at
http://cran.r-project.org/doc/manuals/r-devel/R-exts.html#Embedding-R-under-Unix_002dalikes
should be updated to reflect the change.

Thanks,
Kevin
